We install replacement air conditioners in Lino Lakes for $5,200–$9,800, sized by Manual J with a matched coil and a written quote. Lakeside walkouts often need two-stage equipment or zoning so the lower level doesn't stay humid.
Lino Lakes AC replacements are mostly first-generation swaps in 1990s and 2000s houses. The indoor coil has to match the new condenser and fit the furnace below it, and if that furnace is the original, replacing both lets us match the blower. Line sets usually run from a lower-level mechanical room through the rim joist to a pad nearby, and if they're the right size and in good shape, they can stay.
Walkouts facing the lakes are the design problem. A single-stage unit sized to the upstairs leaves the lower level humid, so two-stage or variable-speed equipment, zoning or a dehumidifier gets priced alongside it. Associations in some neighborhoods set rules on condenser location and screening. Xcel Energy runs cooling and heat pump rebates, some through registered contractors, and Connexus has its own list. With gas from Xcel or Centennial Utilities in the basement, adding a heat pump to work with the furnace deserves a price.

What moves an AC quote within that range: tonnage from the Manual J load calculation, the SEER2 rating, a new coil and line set, and any electrical work. See the AC replacement cost guide or furnace and AC together.
It's worth pricing. Connexus lists rebates for air-source and ductless heat pumps as well as air conditioners, and it runs a reduced-rate heat pump program for dual-fuel systems, where the furnace takes over during control periods or deep cold. That can make a heat pump cheaper to run than you'd expect. Ask Connexus what's current and whether its rebate needs a registered contractor. Heat pumps run $7,500–$14,500 installed with us.
That depends on the model and where it sits. Spec sheets list a sound rating in decibels, and two-stage and variable-speed units are noticeably quieter on low speed, which is where they run most of the summer. Placing the condenser off the deck's corner, away from bedroom windows and not tucked into an inside corner that echoes, helps as much as the model does. We'll show you the ratings.
